It provides a standardized mechanism for using APU. It supports dnl embedding APU into the application source, or locating an installed dnl copy of APU. dnl dnl APR_FIND_APU(srcdir, builddir, implicit-install-check, acceptable-majors, dnl detailed-check) dnl dnl where srcdir is the location of the bundled APU source directory, or dnl empty if source is not bundled. dnl dnl where builddir is the location where the bundled APU will be built, dnl or empty if the build will occur in the srcdir. dnl dnl where implicit-install-check set to 1 indicates if there is no dnl --with-apr-util option specified, we will look for installed copies. dnl dnl where acceptable-majors is a space separated list of acceptable major dnl version numbers. Often only a single major version will be acceptable. dnl If multiple versions are specified, and --with-apr-util=PREFIX or the dnl implicit installed search are used, then the first (leftmost) version dnl in the list that is found will be used. Currently defaults to [0 1]. dnl dnl where detailed-check is an M4 macro which sets the apu_acceptable to dnl either "yes" or "no". The macro will be invoked for each installed dnl copy of APU found, with the apu_config variable set appropriately. dnl Only installed copies of APU which are considered acceptable by dnl this macro will be considered found. If no installed copies are dnl considered acceptable by this macro, apu_found will be set to either dnl either "no" or "reconfig". dnl dnl Sets the following variables on exit: dnl dnl apu_found : "yes", "no", "reconfig" dnl dnl apu_config : If the apu-config tool exists, this refers to it. If dnl apu_found is "reconfig", then the bundled directory dnl should be reconfigured *before* using apu_config. dnl dnl Note: this macro file assumes that apr-config has been installed; it dnl is normally considered a required part of an APR installation. dnl dnl Note: At this time, we cannot find *both* a source dir and a build dir. dnl If both are available, the build directory should be passed to dnl the --with-apr-util switch. dnl dnl Note: the installation layout is presumed to follow the standard dnl PREFIX/lib and PREFIX/include pattern. If the APU config file dnl is available (and can be found), then non-standard layouts are dnl possible, since it will be described in the config file. dnl dnl If a bundled source directory is available and needs to be (re)configured, dnl then apu_found is set to "reconfig". The caller should reconfigure the dnl (passed-in) source directory, placing the result in the build directory, dnl as appropriate. dnl dnl If apu_found is "yes" or "reconfig", then the caller should use the dnl value of apu_config to fetch any necessary build/link information. dnl AC_DEFUN([APR_FIND_APU], [ apu_found="no" if test "$target_os" = "os2-emx"; then # Scripts don't pass test -x on OS/2 TEST_X="test -f" else TEST_X="test -x" fi ifelse([$4], [], [ ifdef(AC_WARNING,([$0: missing argument 4 (acceptable-majors): Defaulting to APU 0.x then APU 1.x])) acceptable_majors="0 1" ], [acceptable_majors="$4"]) apu_temp_acceptable_apu_config="" for apu_temp_major in $acceptable_majors do case $apu_temp_major in 0) apu_temp_acceptable_apu_config="$apu_temp_acceptable_apu_config apu-config" ;; *) apu_temp_acceptable_apu_config="$apu_temp_acceptable_apu_config apu-$apu_temp_major-config" ;; esac done AC_MSG_CHECKING(for APR-util) AC_ARG_WITH(apr-util, [ --with-apr-util=PATH prefix for installed APU or the full path to apu-config], [ if test "$withval" = "no" || test "$withval" = "yes"; then AC_MSG_ERROR([--with-apr-util requires a directory or file to be provided]) fi for apu_temp_apu_config_file in $apu_temp_acceptable_apu_config do for lookdir in "$withval/bin" "$withval" do if $TEST_X "$lookdir/$apu_temp_apu_config_file"; then apu_config="$lookdir/$apu_temp_apu_config_file" ifelse([$5], [], [], [ apu_acceptable="yes" $5 if test "$apu_acceptable" != "yes"; then AC_MSG_WARN([Found APU in $apu_config, but it is considered unacceptable]) continue fi]) apu_found="yes" break 2 fi done done if test "$apu_found" != "yes" && $TEST_X "$withval" && $withval --help > /dev/null 2>&1 ; then apu_config="$withval" ifelse([$5], [], [apu_found="yes"], [ apu_acceptable="yes" $5 if test "$apu_acceptable" = "yes"; then apu_found="yes" fi]) fi dnl if --with-apr-util is used, it is a fatal error for its argument dnl to be invalid if test "$apu_found" != "yes"; then AC_MSG_ERROR([the --with-apr-util parameter is incorrect.
